gramercyjam Posted December 3, 2003 Share Posted December 3, 2003 Not exactly Z stuff, but wondering if anybody knows what kinds of things you can do to one of these GM transmissions to pep it up. It's in a '96 corvette LT1 with the factory high performance suspension. I pretty much have always disliked the soft 1-2 and 2-3 upshifts as well as the lazy and usually inappropriate down shifts everytime I mash the go pedal.

Tim240z Posted December 3, 2003 Share Posted December 3, 2003 The shift points are computer controlled. You can change the point and firmness by editting the PCM. TunerCat has these functions. I have a M6, so I haven't played with changing the A4 functions, but should be pretty easy....probably just slide bars in the software.

gramercyjam Posted December 3, 2003 Author Share Posted December 3, 2003 Doesn't look like Tuner Cat supports '96, at least I didn't see it. Aparrently ODBII is hard. Found LT1 edit at carputing.com but it is $550 and locked to 1 PCM. Know of any others? Quote Link to comment Share on other sites More sharing options...
Tim240z Posted December 3, 2003 Share Posted December 3, 2003 Yeah, TunerCat is OBDI only....

mas28O Posted December 3, 2003 Share Posted December 3, 2003 I am using the stock 4l60e and I love it. I had to play with the shift points using Tunercat but now it works good. If I was you I would use a obd1 ecu. mike Quote Link to comment Share on other sites More sharing options...
